SPECIFICATION forming part of Letters Patent No. 406,692, dated July 9,1889. Application filed March 12, 1889. Serial No. 302,957. (NomodeL) Toall whom it may concern:

Be it known that I, THOMAS B. ATTERBURY, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented new and useful Improyements in the Method ofOrnamenting Open-Ended Glassware; and I do hereby declare the followingto be a full, clear, and exact description of said invention, referencebeing had to the accompanying drawings, and to the letters or figures ofreference marked thereon, which form a part of this specification.

The invention relates to an improved method of ornamenting open-endedglassware, such as hand-blown lamp chimneys, shades, globes, &c.

The object of my invent-ion is to ornamen lamp-chimneys, lamp shades,globes, &c., with various ornaments in depression or relief, as well asto give to the same irregular forms in the way of moldings, flutings,and the like, which has heretofore been found impracticable.

The method consists in closing one end of the article in a former havingthe ornamental configuration to be given to the article, and closing theopposite end and causing the heated article to be forced or to assumethe shape of the former by means of a blow-pipe.

The method further consists in blowing the article and-finishing it in aplain form without the aid of a mold, then placing the article in ablow-snap, reheating the end to be ornamented, placing the heated end ina former having a movable bottom, moving the movable bottom upward toornament the top of the article, making the same air-tight, and finallyblowing through the snap to fill the still plastic glass into theornamented portion of the former, all as will be more fully hereinafterdescribed. y

In the manufacture of lamp chimneys, shades, &c., the mostdesirable andsalable are those made by hand i. 8., as contradistinguished from thearticles blown or pressed in a mold--for the reason that the hand-madearticles are free from scams or ridges caused by the joints of the mold,and it is to improve this class of chimneys that my invention isspecially applicable. Herein g corrugated form.

tofore this class of goods has only been ornamented to a very limitedextentsuch as flaring, crimping, beading, 85c, and this has beenconfined to the extreme upper portion of the article; but by myinvention I am enabled to ornament these articles for almost any portionof their length, and thus give verybeautiful results at a very slightcost over the expense of the ordinary article.-

In carrying out my method I have designed the devices shown in theaccompanying drawings to illustrate one manner of accomplishing the end,and in which- Figure 1 is a transverse section of the former, showing alamp-chimney held by a blow-snap and showing the movable bottom to theformer to give the ornamental configuration to the top of the article.Fig. 2 is a plan or top view of one form of movable bottom. Fig. 3 is aView of a lamp-chimney or namented in accordance with my method.

A suitable frame A has mounted thereon a divided former B, having on itsface the ornamentalconfiguration it is desired to give to the article,and having a flaring open end, as shown at B, to accommodate the size ofthe article. This former B is preferably made in two parts dividedvertically and hinged or otherwise joined at one side and having a suitable catch or holder at the other.

' The lower end of the formerB is made flar ing and is fluted orcorrugated to give to the end of the article the flaring corrugatedform, as shown at C.

The former B above the contracted end of the fluted portion is providedwith a depressed ornamented portion D, (shown in the former B, and inconnection therewith to give to the end or top of the article the flar-This plunger is mounted in a suitable guideway in the frame and isoperated by a foot-lever F, or may be op Y snap G consists of a base g,

' blow-snap and the end inserted in the gloryhole to reheat it. The endis then placed in the former and thrust down upon the former or plunger.The pressure is then applied to the movable bottom or plunger, whichwill expand the end of the chimney and give to the same the flaringfluted form, substantially as shown in Fig. 3. This will form anair-tight joint at this end, and when blowing in the pipe the articlewill be forced out or expanded into the ornamented portion of the mold.

While the devices and the means for operating the same have been foundvery desirable for carrying out my method, still it will be readily seenthat various modifications may be made therein without departing fromthe spirit or intent of my invention. It will also be seen that by mymethod I am enabled to ornament the articles for almost any portion oftheir length, andthus give very beautiful results.

In an application filed of even date herewith, Serial No. 302,958, Ihave claimed the apparatus for ornamenting open-ended glassware, andsuch I do not claim in this application.

Having now described my improved in ethod and one means for carrying thesame into effect, what I claim, and desire to secure by Letters Patent,is

1. The method of ornamenting open-ended assume the the aid of a mold,then placing the article in a blow-snap, reheating the portion to beornamented, placing the heated end in a former having a movable bottom,moving the movable bottom upward to ornament the top, making the sameair-tight, and finally blowing through the snap to fill the stillplastic glass into the ornamented portion of the former, as set forth.

In testimony whereof I affix my signature in the presence of twosubscribing witnesses.
